University Land Grabs in Africa and Student Activism

Major American universities are practicing "land-grabbing" - buying up African farmland in deals that will likely result in displacement of small farmers, environmental devastation and the further impoverishment and political destabilization. Students and alumni: you have the power to change this.

Drought and the Food, Water and Energy Nexus

We're experiencing the food, water and energy nexus first-hand. The worst drought since 1956 might produce significant impacts on food and fuel prices and could cause urban water supplies in some US regions to dry up.

Industrial Agriculture

Most food in the US is now produced on large-scale industrial crop and livestock operations. Learn how this differs from sustainable agriculture - and why it matters.

The Rush To Corn-Based Ethanol: Not All Biofuels are Created Equal

While global demand for fossil fuels grows, gasoline prices remain volatile. Add in concerns about climate change and alternatives to oil-based fuels look increasingly attractive. However, corn-based ethanol, the most prominent biofuel in the United States, will not answer any of these issues.

Biofuels

Biofuels, like ethanol and biodiesel, are derived from living or recently living material that has been converted to liquid fuel to be used in engines, cars or trucks.

Energy and Agriculture

As a result of the industrialization and consolidation of agriculture, food production has become increasingly dependent on energy derived from fossil fuels. Food crops are also becoming fuels themselves.

The Water Footprint Network (WFN)

Home to the water footprint concept and discipline. With over a 100 international partners, the WFN is and the preeminent source for water footprinting research. Numerous studies are available.

The Impact of Ethanol Use on Food Prices and Greenhouse-Gas Emissions

Over the past several years, spurred by both rising gasoline prices and long-standing subsidies for producing ethanol, the use of ethanol as a motor fuel in the United States has grown at an annual average rate of nearly 25 percent.U.S. consumption of ethanol last year exceeded 9 billion gallons--a record high. CBO released a paper today that discusses the relationship between ethanol, greenhouse-gas emissions, food prices, and federal spending on nutrition programs.

Water Embodied in Bioethanol in the United States

"Prior studies have estimated that a liter of bioethanol requires 263−784 L of water from corn farm to fuel pump, but these estimates have failed to account for the widely varied regional irrigation practices. By using regional time-series agricultural and ethanol production data in the U.S., this paper estimates the state-level field-to-pump water requirement of bioethanol across the nation. The results indicate that bioethanol’s water requirements can range from 5 to 2138 L per liter of ethanol depending on regional irrigation practices. The results also show that as the ethanol industry expands to areas that apply more irrigated water than others, consumptive water appropriation by bioethanol in the U.S. has increased 246% from 1.9 to 6.1 trillion liters between 2005 and 2008, whereas U.S. bioethanol production has increased only 133% from 15 to 34 billion liters during the same period. The results highlight the need to take regional specifics into account when implementing biofuel mandates."

Pollan’s Classic 'Food Rules' Is Now a Beautiful Animation

It started with a simple idea: when it comes to food, we should model our diets after that of our grandparents, which is to say, we should eat less meat and less processed food. Michael Pollan’s Food Rules, the slim handbook that answers the common question, "What should I eat?" is sweetly animated here.

Food, Water and Energy: Know the Nexus

"Food, Water and Energy: Know the Nexus" describes how and where food, water and energy systems intersect, how they rely upon each other to function and how they can have a significant impact on each other.

The Nexus by the Numbers

Looking for evidence of how the United States' food, water and energy are connected? Here are a few statistics to illustrate the intersections.
